Cool Disconnecting trailing coil?

Can anyone describe to me what the trailing coil plug looks like? Ive got serious bucking issues under load and I was thinking it was ignition. I checked the timing on all of the wires and the leading was spot on. T1 is spot on but T2, although the timing light blinks as if its firing, I cant see the timing marks on the pully AT ALL. So I was thinking of unplugging the trailing coil to test and see if the bucking goes away. However I figured just unplugging the spark plug wire was not the best way of going about it. I tried looking for the plug but there is a couple of them under the trailing coil and I cant see a clear indication in the FSM as to which plug it is. Or if there is a way to ground the spark from the trailing coil (sounds like a bad idea to me too) to keep it from jumping everywhere.

Unplug both trail plugs. Done

You've a clamp on the timing light that surrounds the sparkplug wire? Yes

. So on the wire that SEEMS to be firing at random, just reverse the way your clamp is on THAT wire. It will now fire in a regular pattern

I mean the electrical plugs to the whole unit. NOT the sparkplugs. Just in case. And you lose your tach doing this.

Yeah I figured you meant that. As for the spark itself, on the T2 side it does not matter which way I turn or place the clamp, you just cannot see the timing marks on the pully when it fires. It does fire rapidly enough that I know I should be able to see the marks, I just dont. It leads me to believe the T2 coil is just firing at the wrong time.

Fudge. I screwed up. You won't ever see T2 and a mark. I was thinking L2 and sure enough you wrote T2. Sorry 'bout that.

It's the plug connected to the trailing coil wires, two of them actually. How hard can that be to find? Follow the wires from the coil to the plugs a few inches away.

Ive got serious bucking issues under load and I was thinking it was ignition.
Only the leading ignition could cause serious hesitation, as the leading plugs do most of the work. You'd barely notice if the trailing plugs weren't firing. Look elsewhere for the cause...
